Hi All,
speaking of Marshalls Bluetooth speakers, what is their rated secondary supply voltage ? I once fixed a Tufton with a 3rd party 24V supply and it worked well, but later I heard it used to have an 18V.
I now have a bad "Stanmore Multiroom" and before I try to dissect the power supply (full of rubber gum), I wanted to test the rest of the unit. But supplying voltage from anywhere between 18 and 21V nothing happened. It just draw around 180-190mA.
